So . . . IMO, really one of the best sources for raiding ideas period? Sounds funny, but its from another game property- West End Game's Pirates & Privateers from the original Star Wars material. I LOVE that book and its one of the three SW books they produced that I carry information over to other settings. It gets into a lot of information about how to run a successful operation (aka unit)- FREX, the Alliance privateer (Grey Claw) that is the contact/study for the author discusses two important things for his ship. He wants his crew to have fresh/good food and they keep the temperature warmer in crew spaces than what would be the norm on a military or commercial ship (though this may not be backed scientifically as a laymen's knowledge of space at the time- it could be said you keep it cooler since the ship has to already radiate away a lot of heat b/c of vacuum). Why? Because it keeps crew morale up and lets him retain crew at a higher rate than other ships.
The book covers how to plan a cruise (or raid in our case), finding targets & learning about them (and the importance thereof), what could be considered valuable & to who- how to turn objects into cash, and some discussion of how to avoid law/military responses.
As far as gaining actionable intel . . . gaining information is SO easy . . . its a matter of learning to put the pieces together. Best example I can think of . . . I worked in a vet hospital years ago. Our near (as in 15 minutes down the road) base was AF and we had a lot of AF members as clients- besides haircuits it was easy to pick them out since they would come in uniform. Some knew I was a veteran . . . one told me she was a squadron XO (mostly knew b/c her uniform) . . . a month or so after the conversation she comes in to pick up some supplies for her dog, pay for a service ahead of time, and arrange for someone else to legally sign off on care for her pet. She was not the first AF person in the last few days . . . so I asked . . . "Squadron's headed to World Hotspot At That Time?" She looked at me, smiled a bit and gave me Standard Answer #1 to Questions about Mobilization. I laughed a bit and told her I had said the same thing a time or two in '02 & '03.
So outside a military base . . . suddenly younger people with specific haircuts start making arrangements for their pets and dropping local college/university classes? Deployment. Lots of the same type of people start start selling their cars and other property? Unit is rotating out for another station and they do not want to haul crap. A single person with the haircut selling stuff? They are PCS'ing to somewhere else.
Ever watch the movie 'Spy Game' with Brad Pitt and Robert Redford? During Pitt's training phase they actually cover some of the little details you can pick up to learn about people.
Another base I used to live around, and have to report to, had a interstate highway (probably back to Ike's day) slicing through a edge and a main round that ran along its southern boundary. People tend to forget that the Interstate Highway system Ike pushed through was, like the digital highway, a national security development that provided commerical/civilian benefits but that was not what it was built to accomplish. So it was always amusing to hear civilians in that military city complain about how the highway lay, the way the exits were near the base, and some of the things it caused- if not for the base, the town would have blown away decades ago and never had a highway connection in the first place. BUT while the highway was built to connect that army base with a AF one to the SW and another AF one to the N, it was also built to prevent casual observation of the cantonment from the highway. The road cut through a minor hill for part of where it bisected the base, a exit was complicated to keep anyone from exiting the highway on the south side of the base being able to observe the airfield & hangers, training barracks were built up against the highway, and a few other things that seem innocent . . . until you think about WHY and especially IF you had been on base so you knew where things were positioned.
After 60 years, and with the highways being turned over to the state, when a road's over pass was being rebuilt . . . well, the state 'simplified' the exit that was specifically built to prevent any drivers from getting a view on base . . . which just happened to give a view towards the airfield. I am sure it was cheaper to rebuild the section that way but no one on the planning committee probably ever gave a thought to security. But someone did . . . the base needed new housing . . . and guess where all the new housing suddenly started being built? Along that edge of the base, the new duplex housing sprung up as a 'visual' fence to prevent observers from watching the portion of the base that would be visible.
Ironic part? Hardly anything ever happened on that airfield- it was a sort of 'spare' facility since the Army Air Force became the Air Force with their own bases. The point of it is that you can always get SOME information . . . the problem usually you get too MUCH information, and you have to put things together.
One other thing it comes down to . . . no raid has to be unprofitable if you win. If you have gained control of the environment, there is ALWAYS something that can be taken. A well planned raid will have a list of primary, secondary and tertiary objectives where you have identified the low-volume/high-value items to be taken- which will mostly be finished product; jewels, gold, silver, platinum, radioactives?, liquor, bundles of cash, tech, data(!!!!), weapons, ammo, art, and BT classics like fusion reactors or water filters.
